HYBRID ENERGY SOLUTIONS: HYDROGEN INTEGRATION IN FLOATING PRODUCTION STORAGE AND OFFLOADING UNITS
Abstract
Hydrogen integration represents a promising strategy for decarbonizing Floating Production, Storage and Offloading (FPSO) operations, which traditionally rely on gas turbines and diesel generators. This study proposes a hybrid FPSO concept combining renewable energy generation with onboard hydrogen production, storage, and utilization. The system emphasizes green hydrogen produced by renewable-powered electrolysis of desalinated seawater, supported by blue hydrogen from associated gas reforming with carbon capture as a transitional approach. Hydrogen serves both as an energy carrier and storage medium, powering fuel cells and hydrogen-compatible turbines to maintain reliable, low-emission operation under variable offshore conditions. Key technical considerations-including electrolyzer integration, hydrogen storage safety, load management, energy dispatch optimization, and system performance under harsh marine environments-are analyzed. The study emphasizes how integrating hydrogen and renewable energy could strengthen operational capacity, lower the environmental impact of offshore activities, and significantly improve energy efficiency. This hybrid strategy offers a feasible approach to support the global trend toward renewable energy and sustainable offshore oil production, demonstrating that it is possible to convert traditional FPSOs into sustainable offshore energy that can process hydrocarbons and produce clean fuels.
